Tree-killing bark beetles are major disturbance agents affecting coniferous forest ecosystems. The role of environmental conditions on driving beetle outbreaks is becoming increasingly important as global climatic change alters environmental factors, such as drought stress, that, in turn, govern...

Characterizing the changes in host tree chemistry after cutting and revisiting the nutritional role of fungi in the novel mountain pine beetle host jack pine
DownloadFall 2018
Studies with conifer-infesting bark beetles commonly use tree bolts to evaluate the effects of host tree quality on various aspects of insect biology. Yet, whether host quality changes between live trees and bolts cut from these trees has not been assessed. Particularly, changes in concentrations...

Chemotypic variations of lodgepole pine affect mountain pine beetle behaviour and growth of its symbiotic fungus
DownloadSpring 2020
Plants generally show large chemotypic variations in susceptibility to phytophagous insects and pathogens. Plant chemical defenses, or secondary compounds, are important components of plant resistance to pest organisms. Among plants, coniferous trees produce complex oleoresins that contain toxic...

Roe, Amanda, Rice, Adrianne, Coltman, David, Cooke, Janice, Sperling, Felix
Grosmannia clavigera is a fungal pathogen of pine forests in western North America and a symbiotic associate of two sister bark beetles: Dendroctonus ponderosae and D. jeffreyi. This fungus and its beetle associate D. ponderosae are expanding in large epidemics in western North America. Using the...

Comparison of lodgepole and jack pine constitutive and induced resin chemistry: implications for range expansion by the mountain pine beetle, Dendroctonus ponderosae, (Coleoptera: Curculionidae)

Clark, Erin L., Carroll, Allan L., Huber, Dezene P.W., Lindgren, B. Staffan, Pitt, Caitlin
The mountain pine beetle, Dendroctonus ponderosae, is a significant pest of lodgepole pine in British Columbia (BC), where it has recently reached an unprecedented outbreak level. Although it is native to western North America, the beetle can now be viewed as a native invasive because for the...

Coupling mountain pine beetle and forest population dynamics predicts transient outbreaks that are likely to increase in number with climate change
Download2023-09-27
Mountain pine beetle (MPB) in Canada have spread well beyond their historical range. Accurate modelling of the long-term dynamics of MPB is critical for assessing the risk of further expansion and informing management strategies, particularly in the context of climate change and variable forest...

Effect of Environmental Conditions on Flight Capacity in Mountain Pine Beetle (Coleoptera: Curculionidae: Scolytinae)
Download2020-10-01
Wijeranthna, Asha, Evenden, Maya
Mountain pine beetle (Dendroctonus ponderosae Coleoptera: Curculionidae: Scolytinae) is a major pest of pine (Pinaceae) in western North America. Mountain pine beetle has an obligatory dispersal phase during which beetles fly in search of new hosts to colonize. Climatic factors may influence...

Wijerathna, Asha, Evenden, Maya
The mountain pine beetle, Dendroctonus ponderosae Hopkins is a major native pest of pine (Pinus Linnaeus (Pinaceae)) in western North America. Host colonization by mountain pine beetle is associated with an obligatory dispersal phase, during which beetles fly in search of a suitable host....

Interactions of pea leaf weevil (Coleoptera: Curculionidae) with its primary and secondary host plants in Alberta
DownloadFall 2021
The pea leaf weevil, Sitona lineatus Linnaeus (Coleoptera: Curculionidae), is an invasive, oligophagous herbivore that feeds on a variety of legume (Fabales: Fabaceae) plants. Field peas (Pisum sativum) and faba bean (Vicia faba) are the primary host plants of the pea leaf weevil. Adult weevils...

Large-scale insect outbreak homogenizes the spatial structure of ectomycorrhizal fungal communities
Download2019-01-01
Ectomycorrhizal fungi (plant symbionts) are diverse and exist within spatially variable communities that play fundamental roles in the functioning of terrestrial ecosystems. However, the underlying ecological mechanisms that maintain and regulate the spatial structuring of ectomycorrhizal fungal...
